Industrial robots & cobots safety: EU Machinery Regulation 2023/1230 and OSHA guidance

Covers the EU Machinery Regulation (EU) 2023/1230 and its July 2026 Digital Omnibus on AI amendment for robot and cobot safety — manufacturer vs. integrator obligations, substantial modification, conformity assessment for AI-based safety functions, technical documentation, and the 20 January 2027 transition from Directive 2006/42/EC — together with US OSHA and NIOSH guidance on industrial robot hazards, lockout/tagout, and teach-mode safeguarding. Built for robot integrators, machine builders, and production or HSE engineers who need precise, article-level answers; note that the European Commission has not yet published an official guide to the new Regulation. Curated by Kopik from public sources: EUR-Lex / Publications Office of the European Union and European Commission (reuse authorised, Decision 2011/833/EU), EU-OSHA (reproduction authorised with acknowledgement), U.S. OSHA and NIOSH (public domain).

This assistant answers practical questions on the safety of industrial robots and cobots: EU obligations under the Machinery Regulation (EU) 2023/1230, its July 2026 Digital Omnibus on AI amendment, and US guidance from OSHA and NIOSH. It is written for robot integrators, machine builders and production or HSE engineers. Every answer comes from the official texts: EUR-Lex, the European Commission, EU-OSHA, OSHA and NIOSH.

From the Machinery Directive to the Machinery Regulation

The Machinery Regulation (EU) 2023/1230 was adopted on 14 June 2023 and replaces Directive 2006/42/EC. It applies on a mandatory basis from 20 January 2027, although some rules started earlier, such as the requirements for notified bodies (20 January 2024).

Machinery placed on the EU market before 20 January 2027 must comply with Directive 2006/42/EC. The European Commission states that manufacturers may mention on the EU declaration of conformity that such machinery also conforms with the new Regulation, where applicable.

Because it is a Regulation, the text applies directly in every Member State, with no national transposition. The application guide listed on the Commission's machinery page (edition 2.3, published April 2024) covers the Directive 2006/42/EC.

The Directive applied to products placed on the EU market for the first time, and to existing machinery modified to such an extent that it becomes de facto new machinery. Like the Directive, the Regulation combines mandatory essential health and safety requirements with voluntary harmonised standards that reflect the state of the art.

What the new Regulation adds for robots

According to the European Commission, the Regulation adds provisions for machinery with AI-powered safety functions, and cyber-safety provisions for compliance-relevant software, data and safety control systems. It also clarifies when instructions for use and the declaration of conformity may be supplied in digital form.

EU-OSHA notes that it clarifies complex issues such as partly completed machinery and substantial modifications, and better covers new technologies such as autonomous mobile machinery, connected equipment and artificial intelligence.

The Regulation covers machinery and related products: interchangeable equipment, safety components, lifting accessories, chains, ropes and webbing, and removable mechanical transmission devices. It also covers partly completed machinery. Machines are allowed on the market only if, when properly installed, maintained and used as intended or under reasonably foreseeable conditions, they meet the essential health and safety requirements of Annex III.

Article 6(9) also requires EU countries to periodically provide data on accidents or damage to health caused by machinery, using a template provided by the Commission.

Documentation, CE marking and digital instructions

Manufacturers must keep the technical documentation and the EU declaration of conformity available to market surveillance authorities for at least 10 years after the machine is placed on the market or put into service. Where relevant, source code or programming logic must be provided to national authorities on a reasoned request.

Instructions may be digital, but if the user asks at the time of purchase, the manufacturer must provide a paper copy free of charge within one month. The Commission also warns that "voluntary certificates" from bodies not acting as notified bodies are not a recognised means of proving compliance.

Robot safety in the United States

OSHA states that there are currently no specific OSHA standards for the robotics industry. General standards apply instead, such as 29 CFR 1910.212 (general requirements for all machines) and 29 CFR 1910.147 (lockout/tagout).

NIOSH identified 41 robot-related fatalities in the US between 1992 and 2017. It lists struck-by and caught-between hazards, crushing and trapping, slips, trips and falls, and electrical hazards. For robots working close to people, it also notes emerging risks such as unexpected contact and mental stress.

Questions fréquentes

When does the EU Machinery Regulation 2023/1230 become mandatory?

It applies on a mandatory basis from 20 January 2027. Until then, machinery placed on the EU market must comply with Directive 2006/42/EC. Some provisions, such as those on notified bodies, have applied since 20 January 2024.

How long must technical documentation for a machine be kept?

At least 10 years after the machinery or related product is placed on the market or put into service. The EU declaration of conformity must be kept for the same period. Digital declarations of conformity must remain accessible online for the expected lifetime of the machine and in any case for at least 10 years.

Is a voluntary certificate enough to prove that a robot cell complies?

No. The European Commission states that under EU law, voluntary or other additional certificates are not a recognised means of proving compliance and have no value during checks by market surveillance authorities or customs. Only notified bodies may issue certificates of compliance, and only within the area for which they are notified.

What are the main collaborative robot safety modes described by OSHA?

The OSHA Technical Manual describes speed and separation monitoring, hand-guided controls, power and force limiting, and safety-rated monitored stop. Speed and separation monitoring is often combined with power and force limiting, so the robot runs fast when nobody is nearby and slows down when a worker approaches.

Does the Machinery Regulation need national transposition?

No. EU-OSHA explains that, because the requirements are laid down in a Regulation rather than a Directive, they apply directly in the Member States and do not need to be transposed into national law.

Who can answer a compliance question about a specific machine in the EU?

The European Commission recommends contacting the relevant national market surveillance authority, which can help case by case. Commission services only give generic guidance, and only the Court of Justice of the European Union can give a binding interpretation of EU law.
